A Novel Low Voltage, Low Power and High Gain Operational Amplifier Using Negative Resistance and Self Cascode Transistors

In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...

Iontronic microdroplet array for flexible ultrasensitive tactile sensing.

An iontronic microdroplet array (IMA) device, using an ultra-large interfacial capacitance at the highly elastic droplet-electrode contact, has been proposed for flexible tactile sensing applications. The transparent IMA sensors consist of an array of nanoliter droplets sandwiched between two polymeric membranes with patterned transparent electrodes, forming the electrical double layers with re...

Flexible low-voltage polymer thin-film transistors using supercritical CO2-deposited ZrO2 dielectrics.

The fabrication of low-voltage flexible organic thin film transistors using zirconia (ZrO(2)) dielectric layers prepared via supercritical fluid deposition was studied. Continuous, single-phase films of approximately 30 nm thick ZrO(2) were grown on polyimide (PI)/aluminum (Al) substrates at 250 °C via hydrolysis of tetrakis(2,2,6,6-tetramethyl-3,5-heptane-dionato) zirconium in supercritical ca...

Flexible low-voltage organic transistors based on a novel, high-mobility organic semiconductor

Organic thin-film transistors (TFTs) are of interest for a variety of large-area electronics applications, such as flexible active-matrix displays and conformable sensor arrays [1]. Among the challenges in the development of high-performance organic TFTs, especially on flexible polymeric substrates, is to realize organic TFTs that simultaneously provide a large field-effect mobility, a large on...
